Microsoft Direct Push - Question

[bankir]

Hi, I'm using WM6.0

I have several question about Microsoft Direct Push, I greatly appreciate if anyone can answer these questions:

I just setup a direct push through my company's exchange server. Everything works fine but I don't get it:

1. I set my Activesync to sync "As items arrive". Then GRPS will start and start sync'ing with exchange but it will stay on and won't disconnect. Is this normal? GPRS is very expensive in my country, I can't afford to have it on all the time.

2. If I disconnect GPRS and close Activesync, when I reopen it, the configuration of Activesync changes from "As items arrive" back to "Manually" > is this normal?

3. If I set it as "Manually" and close the Activesync and disconnect GPRS and try to send an email to myself. It will not push the email like I expected. I have to either go to COMManager and click on "Microsoft Direct Push", which will turn on my GPRS and will make it stay connected to GPRS.

4. If I use WiFi and send an email to myself, I will not get push email. Unless if I go to Activesync and press "SYNC"

5. If I use BT connection to my laptop and start Activesync. It will only sync with server when Activesync sync'ing with computer.

6. Why does Direct Push doesn't work like a Direct Push, it's more like a Direct Pull to me? I always thought that Direct Push meaning that it will connect to GPRS and retrieve an email and disconnect. JUST LIKE MMS.

7. Is there a way to make it a real Direct Push? like it will connect to GPRS only when I'm about to receive an email. Or it will push the email when I'm connected to WiFi?

Thank you for your help. Any comment or any explanation will do. If anyone has a website that explains this, it'll be great also. I have done researches as usual before I post this email but I can't find any answer.

Thx again

Hi,
Same problem and same question about direct push.

I bought a tytn with WM5 to Orange (France). With VM5, the synchronisation is ok with usb and GPRS / 3G also : The 3G goes up as soon as the usb is disconnected and falls down as soon as USB is re-connected up.
With USB, the scheduling is about 5 mns. With 3G this is really "As items arrive".

Today I use WM6 (schap' s 3.54b) with ROM radio 1.51.00.10. The difference with WM5 is the following: 3G / GPRS with pushmail is ok, but when I connect up the usb, the 3G connection remains active, but I think that it is not used by activesync. I'm not sure.

I think that the directpush works only with the 3G, never with wifi, bluetooth or usb.
However, I do not know what has an influence on connection. Is this WM6, the version of protocol or the version of ROM radio? I have not found any doc yet.
If you have any suggestion...
thanks too

Yes, I read from somewhere that push mail will not work over WiFi or USB. When you are using WiFi or USB, you must click SYNC manually to sync with exchange. It will not push the mail.

I hate that fact that the GPRS won't disconnect after getting an email. MMS works that why, why can't push mail be that way?

GPRS is very expensive in Singapore. I wouldn't use it for Push Mail. I just have to make sure that it's doing it manually not "AS ITEMS ARRIVE". That will hurt my pocket and kill me slowly with bills.

A simple explanation would be necessary...

What is push mail ?
Push mail is when the server send a signal to your device so the latest can sync an retrieve any new event signaled. What it means is your device must be reachable from the outside world : your device NEEDS an IP address.

So yes, GPRS (EGDE, 3G, whatever...) needs to be activated all the time, or else the server won't know how to send a signal to your device.

This is like asking someone to send you some package without giving him the address...

You can replace the GPRS with a Wifi link, btw it would need to be always on, and I mean real ON, not the device falling a sleep. The PDA would run out of power in less than 2 hours.

Via Activesync ? Good try. Unfortunally although the device has an IP address, this one is not reachable outside from the computer. Only Activesync classical synchronisation can do the job.

Hope this help.

Then, how can you explain how MMS work? How can the GPRS turn on automatically when there is an MMS and disconnects after it finishes downloading the MMS?

Doesn't Blackberry do that?

For blackberry, you need a gateway to format all messages from exchange to cell phone.

Only to supplement explanation: The pda opens a session via the 3G on exchange server.The channel is so supported opened. At the arrival of a message exchange point out in the pda that he must synchronize. Then it is the habitual process activesync...

But i don't know why the 3G connection isn't disconnected when i plug the craddle. May be the version of protocole version ?

Blackberry also has an always on GPRS connection/
